Business Introduction Email Templates: Cold, Warm and Referral Intros

An introduction email has one job: earn a reply. Most fail because they talk about the sender for six paragraphs and ask for "a quick call" with no reason. The four templates below are short, specific and built around the reader's problem. Copy them, replace the placeholders, and send them from a name@yourdomain address so the first impression is of a real company rather than a free webmail account.

Quick summary

• Under 120 words for a cold intro; under 180 for a warm or referral intro.
• One ask, phrased as a yes/no question, in the last line.
• Name the specific reason you chose them (a post, a hire, a product change), never "I came across your company".
• Send from firstname.lastname@yourdomain.com with a plain signature. Cold intros from a free webmail address are filtered harder and trusted less; on OquMail a domain mailbox is free, so there is no excuse.
• Never attach files to a first email. Link if you must.

Rules that apply to every intro

• Under 120 words for a cold intro; under 180 for a warm or referral intro.
• One ask, phrased as a yes/no question, in the last line.
• Name the specific reason you chose them (a post, a hire, a product change), never "I came across your company".
• Send from firstname.lastname@yourdomain.com with a plain signature. Cold intros from a free webmail address are filtered harder and trusted less; on OquMail a domain mailbox is free, so there is no excuse.
• Never attach files to a first email. Link if you must.

Subject line options

• Cold: "[Their company] + [your company]" or "Question about [specific thing they do]"
• Warm: "Following up from [event / mutual contact]"
• Referral: "[Referrer name] suggested I reach out"
• Mutual intro reply: "Re: Intro: [Name] <> [Name]" (keep the thread the introducer started)

Template 1: cold introduction

Subject: Question about [specific process] at [Their company]

Hi [First name],

I noticed [specific, verifiable observation: e.g. you opened a second branch in Mombasa last month / your careers page lists three sales roles].

We help [type of business] with [one-line outcome, e.g. cut invoice chasing by moving it to a shared billing inbox]. [One sentence of proof: a named customer, a number you can defend, or a short result.]

Would it be worth a 15-minute call next week to see if it applies to you? If not, a one-line "no" is completely fine.

Best regards,
[Full name]
[Title], [Company]
[name]@[yourdomain].com | [phone]

Template 2: warm introduction (you have met or spoken)

Subject: Following up from [event / call / conference]

Hi [First name],

Good to meet you at [event] on [day]. You mentioned [specific thing they said], which stuck with me because [brief reason].

As promised, here is [the thing you offered: a link, a short summary, an introduction]. 

If it would help, I can [specific next step, e.g. walk your ops lead through the setup in 20 minutes]. Would [day] or [day] work?

Thanks again for your time,
[Full name]
[Title], [Company]

Template 3: referral introduction (someone gave you their name)

Subject: [Referrer name] suggested I reach out

Hi [First name],

[Referrer full name] at [Referrer company] suggested I get in touch. [He/She/They] mentioned you are [the situation the referrer described, e.g. moving your team off personal Gmail accounts before the audit].

We did the same for [Referrer company / another named client] and [one-line outcome]. I have copied [Referrer first name] so you can check I am not making this up.

Would a short call on [day] suit? Happy to send a two-paragraph summary first if you prefer to read before talking.

Kind regards,
[Full name]
[Title], [Company]

Template 4: replying to a mutual introduction

Subject: Re: Intro: [Introducer] <> [Your name]

Thanks [Introducer first name], moving you to BCC to spare your inbox.

Hi [First name], great to be connected. [Introducer] mentioned [the reason for the intro].

Short version of what we do: [one sentence]. Where I think it could be relevant to you: [one sentence tied to their situation].

Could we find 20 minutes in the next week or two? I am free [two specific slots with time zone]; otherwise send me any time that suits and I will make it work.

Best,
[Full name]
[Title], [Company]

Timing

Send cold and referral intros on Tuesday to Thursday mornings in the recipient's time zone, and never on a public holiday in their country. Warm intros should go within 24 hours of the meeting while you are still remembered. Reply to a mutual introduction the same day; the introducer is watching and slow replies embarrass them. If there is no answer, follow up once after four working days and once more after another week, then stop. A three-step follow-up sequence is covered in a separate guide on this site.

Mistakes that kill reply rates

• Opening with your company history. Nobody replies to a biography.
• Vague asks: "let me know if you would like to learn more" gives the reader nothing to say yes to.
• Sending from a free webmail address or a no-reply address, which reads as either amateur or automated.
• Attaching a brochure PDF; it triggers spam filters and signals mass mail.
• Copying six people. Cold intros go to one person.
• Following up with "just bumping this" and no new information.

Common questions

How personal should a cold intro be?

Specific, not intimate. One verifiable detail about their business shows you did the work. Comments on their personal life or photos are unwelcome.

Should I mention pricing in the first email?

Only if it is a genuine differentiator, such as a free tier. Otherwise leave pricing for the call; the first email is about relevance, not cost.

Can I send these through a bulk tool?

Not as introductions. Merge fields and tracking pixels are easy to spot and cheapen the message. Send one at a time from your own mailbox; if you have more than twenty a day, you are doing marketing, which is a different discipline.
